The FBI is helping Pennsylvania State Police and other authorities search for a suspect in a case of possible road rage that left a 28-year-old man dead over the weekend, news organizations are reporting.

The incident happened as Timothy "Asti" Davison was traveling back home to Poland, Maine, after spending the holidays in Orlando to visit his grandfather, uncle and sister, his father, also named Timothy Davison, told the Portland Press Herald.

At about 2:20 a.m. Saturday, he telephoned authorities from his vehicle to say he was being pursued on northbound Interstate 81 near the Maryland-Pennsylvania border, according to WCSH 6.

Davison, a 28-year-old construction foreman and supervisor, told police the vehicle pursuing him was a Ford Ranger-style pickup truck and said the driver was firing a weapon at him, WCSH reports. At about mile marker 3 in Pennsylvania, the motorist in pursuit forced Davison's vehicle into the median and fired several rounds into the vehicle, WCSH reports.

Police found Davison with multiple gunshot wounds and he was taken to York Hospital, where he died, WCSH reports.

"He was a great kid," Timothy Davison of Raymond, Maine, told the Press Herald of his late son.

The younger Timothy Davison worked for his father's company, Engineered Construction Services, also in Raymond, Maine.

The late Timothy Davison did fabrication work and installations, his father said.

"He was the smartest one I had one the crew," the elder Davison said. "He could see the vision and he could build it."

The suspect may have tried to shoot someone else before shooting Davison. Authorities are probing a possible connection between Davison's killing and a shooting eight hours earlier about 30 miles away. Police are comparing the bullets from both incidents to see if they are from the same gun, WMTW reports.

"We have to assume the individual is a violent person and might do this again," Pennsylvania State Trooper Robert Hicks told the news organization.

A friend who grew up with Davison told the news organization that he hopes the suspect is caught so he doesn't hurt anyone else.

"He had a lot of friends and was always working on everything," the friend, Steve Hubble, said. "There was nothing that he couldn't fix or weld or create."
